Zeiss Otus 55mm mailfunction reports as non cpu D800

I was using my zeiss otus 55 on Aperature priority mode and all was fine (using D800). I decided to go to a manual mode and all of a sudden I saw a non cpu lens traingular icon next to an F stop. The F stop indicator shows an F stop of 7. I switched out to a different mode and the same thing remained. Now at any A P or S mode it reports as non cpu. If i go to a lens setting menu, I see anon cpu lens 1 where I can set 55mm and maximum F stop. I can control F stop manually on lens through that but the lens does not 55mm and the camer can not set the F stop itself. I tried taking out the battery, switching out lenses (other nikon lenses work fine 24-70mm etc). I've never went to a manual mode on the camera before with this lens combination.
